The circumference $($perimeter$)$ of an ellipse can be approximated by calculating

an intermediate parameter $h$ :

$h=\frac{(a-b{)}^2}{(a+b{)}^2}$

The approximate circumference can be found from $a,b,$ and $h$ as:

$C$~~$(a+b)(1+\frac{3h}{10+\sqrt[\phantom{2}]{4-3h}})$

Create a script file that defines a and $b$ as $5$ and $10$ respectively, calculates $h,$

and then calculates the final circumference.
